Koppen has been the New England Patriots' starting center since 2003 but missed the majority of 2011 with a fractured left ankle and fibula, suffered in the season opener against the Miami Dolphins which ultimately led to his placement on injured reserve.
While Koppen was out, New England relied on Dan Connolly to fill in as the team's starting center and he certainly was an integral part in the team's appearance in Super Bowl XLVI. In fact, the Patriots re-signed Connolly at the start of free agency to a three-year, $9.7 million contract.
I am not expecting Koppen to return with the Patriots in 2012.
Koppen has had a stellar career with the Patriots as he was the man that anchored one of the league's top offensive lines. That group has done a superb job at protecting Tom Brady throughout the years.
Where ever Koppen may land, all of Patriots fans should wish him the best of luck as he certainly made his impact throughout the dynasty years of the New England Patriots.
